日本語

フィンランドの1940年代から2010年代までの53の住宅コホートを対象に、現在のGWP係数を用いて構造体の体化炭素を推定したデータセット。一戸建てと集合住宅を含み、建物レベルから部材レベルまでの推定値を提供。床面積当たりの炭素原単位も提示し、アーキタイプ間の比較が可能。近隣レベル以上のLCAや、材料ストック・フロー分析との組み合わせに利用できる。

English

This dataset provides embodied carbon estimates for structural materials of 53 Finnish residential building cohorts from the 1940s to 2010s, using present-day GWP coefficients. It covers single-family houses and blocks of flats, offering estimates at building, horizontal, and component levels, as well as floor-area-based intensities for comparison. Useful for neighborhood-level LCA and combined material stock and flow analysis.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では、建築物の脱炭素化に向けてLCAや体化炭素の算定が重要視されており、本データセットは住宅ストックの炭素評価の方法論を提供する。日本の住宅データに応用することで、既存ストックの改修や新築時の炭素削減策の検討に役立つ。

In the global GX context

Globally, embodied carbon in buildings is gaining attention in climate disclosure and LCA frameworks. This dataset provides a replicable methodology for estimating embodied carbon in residential building stocks, which can inform policy on building decarbonization and support alignment with frameworks like the EU Taxonomy and CSRD.

👥 読者別の含意

🔬研究者:Provides a detailed dataset and methodology for embodied carbon estimation in residential buildings, useful for LCA and MSFA research.

🏢実務担当者:Can be used to benchmark embodied carbon in building projects and inform low-carbon material choices.

🏛政策担当者:Offers evidence for setting building carbon limits and developing national databases for embodied carbon.

📄 Abstract（原文）

This dataset contains estimates of embodied carbon in building structures for a total of 53 residential building cohorts in Finland from the 1940s to the 2010s, which have been reconstructed using present-day GWP coefficients. The building types covered are one dwelling houses and blocks of flats. The dataset was created by combining and extending two existing datasets: (1) a building part specific material inventory dataset for residential buildings in Finland, and (2) the generic Finnish national emissions database CO2data. Materials presented in the former dataset were matched with the most appropriate corresponding material in the latter. The volumes and densities of materials were multiplied by the GWP coefficients of present-day Finnish construction materials to approximate the embodied carbon of materials present in structures of Finnish housing archetypes. The resulting embodied carbon estimates are presented at the scale of a building, a horizontal building level, and at smaller scales of components. The embodied carbon estimates are also presented as intensities that divide by the floor area of building archetypes; this enables comparing structural embodied carbon between archetypes. The data can be used for life cycle analysis (LCA) on the neighbourhood level or higher, or combined with the original material inventory dataset, for a combined material stock and flow analysis (MSFA) and LCA.
